Hi Lee
im using M16-10 coupled to a 120 W , 2200 rmp thru a 1:75 box (finished speed 293+-) torque 3.21 NM ..293 x .01 = 2.93m / 60 = .0488 x 20 sec =976mm
( I hope i got it all correct )
Putting it all thru a uniquegoods 12-30V MAX 30A DC Motor Speed Control with Wireless Remote Controller Adjustable Switch Reversible Driver Governor Two Way Version + Limit Function with 2 proximity sensors ( one each end of travel) which changes direction of screw.
I have to sort the wiring out and how to control it all ( 6 button Linear actuactor controller perhaps )
the whole machine slides on SGR 20 tracks with a pair SGB20N bearings each end. It litterally takes a gentle hand push to move from one end to the other.
My Brain has had a bloody good workout but still not really up on the electrics stc.
Had help from other forums to get me this far.
The machine is a "thing of beauty " .. At least i think so :0)
Thanks for your interest
Richard
